Thanks John and Marcus for your feedback; John, I may take you up on that after I check with some people. I'll let you know how it works out!
As others will confirm, what you are asking to do is a hard computer
science problem. We developed some Java code for doing what you want with
Swarm called Syncer back in 2000. Unfortunately it was never updated with
the newer releases of Swarm and the last time we checked it out, it would
not run with Swarm any longer. I would be willing to send you the paper
describing the algorithm and the source code if you want to try and get it
to work with the current releases.
You can also check out a paper by Matthias Scheutz entitled, "Adaptive
Algorithms for the Dynamic Distribution and Parallel Execution of
Agent-Based Models". A copy can be found at:
http://www.nd.edu/~airolab/publications/scheutzschermerhorn06pardist.pdf
Finally, back in '02 I was in communication with Andy Cleary at Lawrence
Livermore who haunts these mailing lists on occasion. He was working on
distributing Swarm over a 1000+ node tightly coupled architecture. He may
be able to help.

AM [Swarm-Modelling] Question about
Distributed Simulations
Please respond to
Agent-based
modeling
<address@hidden
org>
Hello list,
I'm not sure which is the correct list for this question so my
apologies in advance. I am looking into the feasibility of running a
Swarm simulation on IBM's Blue Gene L, which has as its base rack a
1000 node cluster (2000 PPC 5 processors). The question is whether an
individual run could be done across the entire cluster, with groups of
agents distributed among all the nodes and communication across the
nodes. I recall threads having to with distributed simulations but
cannot remember if that was distribution for batch runs or for a single
run. If this has been extensively discussed perhaps someone could point
me towards that archived thread? Thanks in advance.
